    Wormhole
AI Thread Summary
Euclidean wormholes are theoretical constructs in quantum mechanics that differ from Lorentzian wormholes, which involve black holes and white holes. There is currently no empirical evidence supporting the existence of any type of wormholes, as they remain speculative within the framework of general relativity. Most theoretical models suggest that wormholes would require exotic matter with negative energy density, but this has not been definitively proven. The existence of Euclidean wormholes and their properties remain uncertain, highlighting the need for a viable theory of quantum gravity to explore these concepts further. Understanding Euclidean wormholes requires delving into complex quantum mechanics rather than relying solely on general relativity.

I have a question wormholes. I know the loretzian wormholehas a black hole and the theoretical white hole. The Euclidean wormhole I don't know anything about. All I know is that they are from quantum mechanics. Can I have a non mathematical answer to what they are? Thanks!

There is no evidence wormholes exist, except as potential artifacts of general relativity. One such prediction is a Lorentzian black holes [also known as an Einstein-Rosen bridge]. It is unknown whether such wormholes are possible or not within the framework of general relativity. Most solutions of GR which permit wormholes require exotic matter, a theoretical form of matter that has negative energy density. It has not been mathematically proven this is an absolute requirement, nor has it been proven exotic matter cannot exist. A viable theory of quantum gravity is necessary to draw any conclusions.
 
I unserstand you about Lorentzian wormholes. I wanted to know about the quantum euclidean wormholes
 

Thread 'Potential biosignature found in Mars rock'

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
